Line in

[china_rider]

I always use line in with Sonic Studios DSM6SM  -> PA-3SX -> R-9.

From memory Im remembering that a gain setting of 7-8 on the R-9 is no gain added (+0, unity.. 8 if I remember right).  Anything lower you are attenuating, anything over your are adding gain.  Thats if I remember the others explanation correctly.

Seems like with my setup recording at 24bit I've been running gain at +10-14 which seems to give me about -14 to -6db in the end which gives me plenty of room in post to adjust without clipping while recording.

Stay Kind,
Dana

I run HEBs > CS batt box > R-09 for mostly medium loud rock shows.  I've done both mic in and line in and feel my results are better with line in.  Sorry can't give you any hard numbers re: input, gain.  For years I ran mic in Sonics DSM-6S > D7 so this line in business is new to me but I'm digging it.

Anyone try the Ritek 4GB SD card in an R-09 -

It's the same price of the Transcend (after rebate), but has free shipping this weekend.

Well kind of off topic...

Say, has anyone who purchased the Transcend 4GB SD cards from newegg.com gotten their mail-in rebate yet?

No but I got an e-mail saying it was going to be mailed shortly. Along with a page where I could check the status

Got my rebate back this week.

Nice good to hear,  I should be getting mine soon as well!

Can somebody here please explain the 'level 8 is unity' thing?

The R09 level scale has about 30dB in gain range.
The ADC of the codec chip has about 0.77 Vrms for 0dBFS.
The info at http://www.sonicstudios.com/r-09revw.htm#inputs mentions -13 to +16 dBv for line in.
On that scale 0.77 Vrms is at level 17.
Level 8 gives 2.2 Vrms.

So I am a bit confused.

Just do a search.  It is in this thread or the prior one R-09 announcement thread.
I clearly remember someone posting the results that "level 8" is the perfect level as previously mentioned.

Perfect because of lowest noise?
I can search but not always find. More unity theories are welcome.

It doesn't matter much since the R-09 is low noise on any setting except from 25-30 where it gets more noise.  And you are always going through the R-09 pre even when you use an external pre. So if your pre is quieter than the R-09 pre, you want to do more gain with it and set the R-09 as needed to get around -6db.  The thing to avoid is that many pre's will get exponentially more noisy as they approach the highest gain settings.  Thats why you wouldnt want a setting of <8 usually because then you are attenuating and cranking the external pre up to high.  In many cases using the R-09 pre mic-low gain setting alone will be less noise than the combined noise of your external pre plus the R-09 pre set on line-in.  Testing the self noise at different settings of pre vs R-09 is the only way to tell.

I do not use an external pre. I.e.: no pre at all except the recorder.
You also assume 8 is unity but the Vrms figures speak against this?
I understand your reasoning. And I can mostly agree.
I still don't see an explanation why 8 would be unity.

Look through this thread.  It has been discussed in great detail already.

Thanks for looking stuff up (even one is my own post), but they are just statements and no explanation.
Explanation is what I am after. I want to understand why and how.

Found that. Not sure what you are trying to understand honestly.
